While some of these measurements can be estimated with traditional visual methods, using specialized equipment is crucial for accuracy and safety. Ningbo Changshi offers a range of tools designed for these precise measurements.

• For Sag and Tension: Our hydraulic puller and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner machines are equipped with advanced control systems and can maintain and display precise tension during the stringing process. For post-installation checks, we offer tension meters and sag measurement devices that can be used to verify the line's mechanical state.

• For Clearance: While laser measurement devices and ultrasonic measuring tools are popular for remote, non-contact measurements, we also supply essential measuring tapes and measuring rods for more direct, de-energized work. These tools are often used in conjunction with other methods to ensure compliance with local safety codes.

• Modern Methods: Modern utility companies are increasingly using drones equipped with LiDAR (Light Detection and Ranging) and high-resolution cameras. These tools create detailed 3D models of the power line and its surroundings, allowing for highly accurate sag and clearance measurements from a safe distance.
